[rules-users] Rule activation when using from

[wumb]

Because it's not a fact, it's a global.

What i basically want to do is to have one rule being fired exactly once 
for every call of fireAllRules(). The rule will operate on a global, 
that is why i asked the question this way.

What would be the best/simplest way to fulfill that requirement? I know 
this can be solved by inserting a fact before calling fireAllRules(). 
But i am looking for  a solution which does not envolve "external" fact 
insertion. It should be solved by the rules itself.

Any idea?
